matassa l Specification of Letters Patent. i `Paudjejfljtqd @10th. 23, 1917.

Application led'Decembe'r 13, 19,16. Serial No. 136,617?. 'i i f l To all whom 'it may concern.' 1 Y Be it known that I, LAURENTE Burr, a citizen of the United States, residing in the city, county, and State .of New York, have invented a new and useful Improvement in Beaters or Mixers, of which the following is a specification.

rIhis invention relates to beaters and mixers, and has for its object to construct such articles with but few parts, and in an extremely simple form, and so that they will be at once efficient, easy to use, cheap in construction, and not liable to get out of order. v

These and are set forth in the following specification,

` and shown in the accompanyingdrawings,

the particular features of .novelty which constitute my invention being pointed out in the claims at the end of this specication.

In the drawings, which form a partof this specification, and in which similar let-` Y ters and figures of reference refer to correspondingparts wherever they occur Figure 1 is a central vertical section of one of myimproved' beaters, the agitator stem being shown in full lines;

Fig. 2 is a side elevation of the top portion of the beater shown in Fig. 1;

Fig. 3 is a transverse section taken on the line 1 1 of Fig. 1;

Fig. 4 is a central vertical section of a modied form of my beater;

Fig. 5 is an enlarged detail view of a portion of the agitator and stem shown in Fig. 4, illustrating means for securing them together; and,

Fig. 6 is an enlarged sectional view of a portion of the agitator showing its perforations with their projecting rims.

In the drawings, 1 is an outer container, preferably of cylindrical shape, formed of sheet metal or other desired material, which is provided with a cover 2, adapted to be secured to the top of the container by bayo net joints 3, (see Fig. 2,) or by any other desired fastening means, and with a bottom 4.

The cover 2, and bottom 4, are respectively provided with centrally and f oppositely disposed conical concavities 5, 5, to receive and hold the ends of the agitator stem,

as-hereinafter more fully described.

I form my agitator 6 of a thin sheet'A metal plate, which corresponds in shape and size with the interior of the container, and

other objects of my invention in lthe drawings,

fits within the same transversely and closely.

The agitator 6 is formed with a seriesl of radial corrugations7, forming beating sui faces which are conicallyshapedin cross section, and with numerous perforations 8, which are pricked or punched through the metal from one side tothe other to form ends of a stein 9, by soldering it -thereto,'or

in any otherdesired manner, said stein being sharp, projecting,` irregular rims 21, which Y serve to cut and tear thematerials beingI so formed that its ends will project into the concavities 5,5, in the cover-and bottom of y the container, abuttingvagainst the walls of the-same, and so that the'stem'lwillbe held firmly in'place therebetween when thel cover is fastened-.upon the top of the container.

' Theabottom'4 of the Ycontainer is prefer-l i ably provided with a circumferentialange '10, and is inserted into, and fastened in the end of the container inY such mannerthatthe wall of the concavity 5 will not project be- 'f yond Vtheplane of the end:` ofthe container.

Inv operation, the cover yis first removed,

and the eggs or other materials to be beaten or mixed are placed within the container.

The cover 2'is then placed and fastened'in l position, thereby securing the ends of the stem in the concavities. The container and its contents are then shaken by the user, the contents being thereby forcibly beaten against and through the perforated agitator and its sharp projecting rims 21.v

In a Very brief period of time a thoroughl beating and mixing of the materials will be accomplished by the action of my beater, and its radial, conically shaped corrugations, and the rimmed perforations of the agitator.

In Figs. 4 and 5 I show aimodied form of my invention, in which an elongated stem 12 is employed, one end of which isgpassed through the cover of the container, and is bent around upon itself for the purpose'of forming a handle 14, while the agitator v15 is secured to the other end of the stem.

In this modified form I prefer to con-v top of the agitator, and upset the end 16 of the stem against the underside of the agitator, as shown at 18, and then apply solder 19 over the joint thus formed.

A bushing 2O may be formed in the cover of the container around the opening 17 to' act as a bearing for the stem 12, and also to prevent particles lof the materials being beaten being drawn through the cover to the outside thereof.

The agitator 15 is provided with perforations 8, which are pricked or punched through the metal to form sharp projecting rims therefor, as shown at 21 in Fig. 6.

I, employ the form of beater shown in Figs. 1 to 3 inclusive, when beating or mixing small quantities or materials, the torn shown in Fig. 4 being used when large quantities of' materials are to be beaten or mixed at the same time; in this case the agitator 15 is moved up and down in the container by means. of the handle 14.

Vhat I claim as new and desire to secure by Letters l'Patent` is:-

1. A beater or mixer comprising a con tainer, and an agitator supported trans versely within saidcontainer, said agitator being formed with radial corrugations and raving vperforations arranged along the lines of said corrugations, said corrugati-ons forming radial, eonically shaped beating surfaces.

2. A beater or mixer comprising a con-V tainer, an agitator arranged transversely tainer having a cover and a bottom provided with oppositely arranged conieally shaped eoncavities, a stem held between the walls of said concavities, and an agitator having radial corrugations each of said corrugations being provided with a yseries ot perforations along its length.

5. A beater or mixer comprising a oontainer havinga cover and a bottom provided with oppositely arranged eonieally shaped eoncavities, a stem held rigidly between` the walls of saidv concavities, and a radirdly corrugated transverse agitator having perforations formed Valongthe` lines of the corrug-ation@ said agitatorbeing secured to said stem between its ends.`

In testimony whereof, ,I ,have sig-ned my name to this specification, this 18th day of November, 19116.

LAURitiriui` Burr.
